Moses told Joshua to not be afraid when he entered into the promised land.
I googled the phrase and saw this youtube video with a red rose in the caption.
"In 1993, President Bill Clinton chose “Be Not Afraid” to be played at the church service he attended on the morning of his inauguration. The former president wrote in his autobiography that the song was “one of my favorite hymns and a good lesson for the day.”'
